SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No.. 694,612, dated March 4, 1902.

Application tiled May 20, 1901. Serial No. 61.002. (No model.)

To all whom, t may concern:

Be it known that I, WILLIAM CARRICK, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements'in Sash-Fasteners, of which the following is a specification.

This invention has for its object to provide a cam-shaped sash-fastener adapted to automatically engage a window-sash and prevent the same from moving either upwardly or downwardly and also adapted to be retracted to an inoperative position to permit the unobstructed movement of the sash intended to be held by the fastener or of the sash on which the fastener is supported. l

The invention consists in the improvements which I will now proceed to describe and claim.

' Of the accompanying drawings, forming a part of this specification, Figure l represents a transverse section through the meeting-rails of two of the sashes of a window, showing a fastener lembodying my invention supported by the lower sash and adapted to engage the .upper sash. Fig. 2 is an 'elevation of the samefromtheinnersideof thewindow. Fig.

3 is a section on line 3 3 of Fig. 2. 'Fig. 4 is.

a view similar to a portion of Fig. l, showing a different adjustment of the fastener. Fig. 5 represents a view similar to Fig. 3, showing the 'fastener retracted and held in an inoperative position. Fig. Grepresents'a section on line 6 6 of Figs. 5 and 8. Fig. 7 represents a section on line 7 7 of Fig.r3. Fig. 8 represents a top plan view showing the fastener held in the position shown in Fig. 5. Fig. 9

represents, in twov views, a section on line 9 9y of Fig. 5. Fig. l0 represents alperspective view of the button-retracting device hereinafter referred to.

The same reference characters indicate the same parts in all the igures.

In the drawings, a represents a support', which is here shown as a bracket adapted for attachment to the meeting-rail b of the lower sash of a window. c represents a stud affixed to said support.

d represents a button, which is provided with a slot d', through which the stud cpasses,

said slot being formed to permit the button both to oscillate on the stud and to move edgewise toward and from one of the side rails of the upper sash e. The button has a camshaped or eccentric face d'which is ecceng tric to the stud o in any position that the button can assume on the stud and is arranged to bear against the side rail of the upper sash. f represents a spring interposed between 'the stud c and the bottom of a cavity formed lfor the reception of the spring in the button d, said spring tending to force the cam-face d2 yieldingly toward the part of the upper sash on which it bears. It will be seen, therefore, that when the springf is free to act it holds the cam-face of the button yieldingly :in engagement with the upper sash, whether `the button'be in the position shown in Figs.v 1, 2, and 3 or that shown in Fig. 4 or in an intermediate position; Hencethe button is always in a position to act to prevent movement of either sash relatively to the other, the button preventing upward movement of the lower sash and downward movement of the upper sash when in the position shown in Fig. l and preventing downward movement of the lower sash and upward movement of the uppersash when in the position shown in Fig. 4.

The button' is provided with a suitable handle or projection on the side ofthjestud c opposite the cam-face d?, whereby the operator may grasp the button and' retract it, thus withdrawing the cam-face from contact with the upper sash when it is desired to quickly adjust either sash. In the present case the handle or projection is an extension d3 of the body of the button, said extension having curved sides d4 d4, whereby it may be conveniently grasped. l

-I prefer to provide the button with means whereby it may be lockedor secured in a retracted position, so that when it is adjusted to the-intermediate position shown in Fig. 5 it will be held out of contact with the upper sash. Any suitable device may be employed for this purpose. The retracting device here shown is a stem g, j ournaled in a socket formed for its reception in the extension of the button and having its inner end slotted to form arms or bifurcations g g', separatedby a slot of greater width than the diameter of the stud c, so that when the stem g is in the position shown in Figs. 3,4,and 7 its arms g' will be free to move lengthwise across the stud c, so that ICO the stem does not adect the freedom of edgewise movement of the button. The inner ends of the arms g have concave or cam-shaped faces g2, which are adapted when the stem is given a quarter-turn to the position shown in Figs. 5 and 6 to engage one side of the stud c, and thus force the button baekwardly and hold it in the retracted position shown in the figures last mentioned. The stem gis prevented from moving endwise independently in the button by means of a key or pin h engaging a peripheral groove 1T in the stem. The stem is preferably provided with a thumbpiece or handle g3, whereby it may be conveniently rotated from one of the positions described to the other.

I do not limit myself to the form and oonstruction of the device herein shown and claimed,as the said form and construction may be variously modiied without departing from the spirit of my invention. In particular the holder a. may be formed for application to any other suitable support, such as the casing of the window, instead of being adapted for attachment to the meeting-rail of the lower sash.

It will be seen that the spring pressing the cam-face of the button against the upper sash prevents rattling of either sash.

The cam-face of the button may have a facing or coating of rubber or other suitable yielding material to prevent the button from indenting the sash on which it bears. The inner edge of said facing is indicated by the dotted line m in Fig. 4.

I claiml. A sash-fastener comprisinga holder having a stud or journal, and a button having a cam-face,a journal-receivingslot whereby the button is adapted both to oseillate and move edgewise on said journal, a spring whereby the cam-face is pressed yieldingly from the journal to automatically bind if oscillated in either direction, and means for looking the button in retracted and inoperative position.

2. Asash-fastener comprising a holder having a stud or journal, and a button having a cam-face,a journal-receiving slot whereby the button is adapted both to oscillate and move edgewise on said journal, and a spring whereby the cam-faeeis pressed yieldingly from the journal, said button having a handle or projection at-the opposite side of the journal from the cam-face, whereby the button may be retracted against the force of the spring,to make its cam-face inoperative.

3. A sash-fastener comprisinga holder having a stud or journal, a button having acamface,a j ournal-reeeivin g slot whereby the button is adapted both to oscillate and to move edgewise on said journal, a spring interposedv between the journal and the cam-face of the button, and a button-retraoting stem journaled in the button and having a cam-shaped inner end bearing on said journal, said stud being prevented from moving endwise in the button.

In testimony whereof I have affixed my signature in presence of two witnesses.

WILLIAM CARRICK.
